METHOD OF MANUFACTURING DISPOSABLE STRAWS AND CUP LIDS
20220071421 · 2022-03-10 ·

The present invention provides a method for the manufacture of disposable straws (preferably having an average length between 10 cm and 30 cm) and cup lids from fibrous materials preferably including paper, cardboard, plant fibers, animal fibers, artificial fibers, fabrics made from one or more thereof; or non-woven materials made from one or more thereof. These manufacturing steps generally and preferably include: (1) feeding a strip of fibrous material into a tank of adhesive or glue for treating fibrous material with a solution of cellulose ester in a solvent; (2) feeding the treated fibrous material into a press or spiral winding unit; (3) drying, cutting, and forming the fibrous material into disposable straws or cup lids; (4) testing the formed disposable straws or cup lids for quality control; and (5) packaging the disposable straws or cup lids.

BOX AND METHOD OF CONSTRUCTING THE SAME
20210316522 · 2021-10-14 · ·

A box suitable for the packaging of a consumer product is formed by helically wrapping an elongated continuous strip of material around a mandrel to form a main body with a plurality of bands. In one embodiment, adjacent bands partially overlie one another to form a multi-paneled main body with an open top end and an open bottom end. An adhesive is disposed within the region of contact between adjacent bands to retain the shape of the main body. First and second sets of slots are formed in the main body to create flaps dimensioned to selectively enclose the open top and bottom ends, respectively. To define the flaps and promote pivotal articulation, the main body is also preferably provided with score lines. By adjusting the configuration of the mandrel, a customized box can be constructed that is sized to receive a consumer product with limited wasted space.

APPARATUS AND METHOD FOR MAKING AND CUTTING PAPER TUBE
20210316469 · 2021-10-14 ·

A paper tube making and cutting machine includes a fixed rod, a paper tape winding mechanism, an angle measurement unit, a length measurement unit, a cutter, and a drive mechanism. The paper tape winding mechanism wraps or winds at least one paper tape around the fixed rod to form a paper tube. The angle measurement unit measures an angle of the paper tape winding mechanism or the paper tape relative to the fixed rod. The length measurement unit measures a conveyed length of the paper tape. The drive mechanism determines and sets a moving speed of the cutter along the fixed rod according to the angle and the conveyed length, such that the moving speed of the cutter is corresponding to or close to a producing speed or generation rate of the paper tube formed on the fixed rod, in order to prevent the paper tube from pushing a side surface of the cutter or to prevent the cutter from pulling and stretching the paper tube to thereby improve durability of the cutter and the quality of a cut paper tube.

A system and method for cutting straws. The system includes a cutting device. The cutting device may include a cutting device frame, a tubing guide connected to the cutting device frame for receiving tubing and guiding the tubing into a position to be cut, and a blade spool having a spool central axis. The blade spool may include a spool frame, connected to the cutting device frame, and a blade assembly. The spool frame may rotate with respect to the cutting device frame about the spool central axis. The blade assembly may include a blade shaft connected to the spool frame and a blade connected to the blade shaft. The blade may rotate about the blade shaft central axis and move through the tubing when the tubing is in the position to be cut. In another embodiment, the system may include a winding device and a control monitor.

PROTECTIVE BARRIER COATING FOR TUBES AND CORES

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

An apparatus for forming a box or bag that is made of a substrate strip which includes a winder having a mandrel and posts that extend from the mandrel in a direction parallel to a winding and translation axis that rotate together as a unit around the translation axis. The apparatus also has a feeder that includes precursors and a gathering head used for forming the precursors into the strip and feeding the strip to the winder. A motor adjusts the feeder's angle relative to the winder in response to instructions from the controller based on the dimensions of the box or bag. This causes controlled overlap between adjacent windings of the strip on the posts. As the mandrel rotates, the posts draw the strip and wind the strip along a spiral having a length in excess of the depth. Zero waste of precursors is made possible by cutting the substrate perpendicular to its length and folding over the box or bag ends to form an angled seam with respect to the sides of the box.
